Dear Don Cragun,

Thank you for your help. Sorry, I am using CentOS release 6.6 server and the SHELL is 4.1.2(1)-release.

Code:
 for line in $(cat list.txt)
do
 grep $line code_to_value.txt | cut -c18 > value_1
 grep $line code_to_value.txt | cut -c22 > value_2

 paste -d "" value_1 value_1 > code_1
 paste -d "" value_1 value_2 > code_2
 paste -d "" value_2 value_2 > code_3

grep -n $line table_values.txt | cut -d : -f1 > line

sed "/$(cat line)/ s/1/$(cat code_1)/g" table_values.txt > test_output
done

I am getting this error.

sed: -e expression #1, char 0: no previous regular expression

Here is a better exemple of the data:

Code:
PT_1 1 1 1 1 1 1 2 2 1 1 2 
PT_2 2 2 3 1 2 3 2 2 1 3 1
PT_3 3 2 3 2 3 3 2 1 1 2 3
PT_4 3 2 1 2 3 1 3 2 1 1 2

Thanks very much for your attention!
Leandro

LEARN ABOUT DEBIAN

fixnt

fixnt(1)							      Debian								  fixnt(1)

NAME

       fixnt - Filter for the Windows NT postscript printer driver.

SYNOPSIS

       fixnt < BADFILE.ps > GOODFILE.ps

DESCRIPTION

       The  Windows  NT  postscript  driver has a tendency to make broken postscript files, that are incompatible with psutils.  fixnt is a filter
       that fixes these problems, allowing the use of psnup(1).

       The filter takes the broken postscript file on stdin, and outputs a fixed postscript file on stdout.  It has no other form  for	invocation
       and takes no options on the command-line.

OPTIONS

       fixnt  takes no options.

BUGS

       fixnt does not check for NTPSOct94.  For a workaround, use a sed(1) command to replace 'NTPSOct94' with 'NTPSOct95', like so:
	      sed 's/NTPSOct94/NTPSOct95/g'
       This is particularly important for Windows NT 3.5 users.

AUTHOR

       fixnt   was   written   by   Holger   Bauer   <Holger.Bauer@topmail.de>,  Michael  Rath	<rath@itsm.uni-stuttgart.de>,  and  Akim  Demaille
       <demaille@inf.enst.fr>.

REPORTING BUGS

       Report bugs to the Authors, but avoid sending large postscript files.

       Patches are always welcome; send to <bauer@itsm.uni-stuttgart.de>.
